Helps if the httpd.conf axkit provider name matches the modules package
name :)
I deserve a kick in the butt after spinning my wheels for 24 hours.

I'm having problems getting Axkit to work. I have tried recompiling perl,
apache and mod_perl with and without large file support and have also
compiled apache with disabling expat. I still get the same error.
Mod_Perl programs work just fine and perl programs as well. The only time I
get these segmentation faults is when I use an Axkit Custom Provider. I've
used Providers before but never encounted the below error. I have had
problems with large file support before but I do no think this is related.
I'm using mod_perl-1.29, perl-5.8.5 apache_1.3.34, Axkit 1.7 (tried 1.62 as
well) and libxml-2.6.17. This is the exact same environment as the other
production/development machines I run.
Any help is appreciated. If you need more details please let me know.
Thanks in advance,

Mostly, when you see programmers, they aren't doing anything. One of the
attractive things about programmers is that you cannot tell whether or not they
are working simply by looking at them. Very often they're sitting there
seemingly drinking coffee and gossiping, or just staring into space. What the
programmer is trying to do is get a handle on all the individual and unrelated
ideas that are scampering around in his head. (Charles M Strauss)
